Science Daily reports that researchers from the University of Stuttgart and the Fraunhofer Institute for Applied Solid State Physics IAF used radio transmission to send the contents of a conventional DVD in under ten seconds, setting a new world record in wireless data transmission. The transmission was clocked at 6 Gigabits per second over 37 kilometers between Cologne and the town of Wachtberg at 71-76 GHz in the so-called E band, regulated for terrestrial and satellite broadcasting. The researchers said they needed to use the millimeter waves of those frequencies to send the data so fast. The group used a highly directive parabolic antenna to send the signals, and say there are several applications for the technology. It could be used offload data from earth observation satellites down to earth, or the terrestrial radio transmissions in the E-band expand rural broadband, and has can be set up quickly for emergency broadcasts.
